No ground loop noise! VLC player can pass the Dolby Digital or DTS signal to the receiver for full surround sound.
If you're trying to do this, expect problems, as PulseAudio doesn't really cope with encoded signal passthrough yet, though I believe someone's working on it.
Fedora 14 (updated) with the current Nvidia driver is reported to support HDMI audio output. By installing the XFCE mixer I am able to activate iec958 1 which outputs an audio bit stream over the HDMI connector.
I don't know if Xfce's mixer is doing the right thing, you may want to install pavucontrol and check the settings there.
Is there a reasonably simple way to get Fedora to speak over the display adapter's HDMI output?
For 'normal' playback (not encoded signal passthrough) it ought to work once you make sure to set the appropriate output for PA. If it still doesn't you'll need to file a bug with the recommended details - https://fedoraproject.org/wiki/How_to_debug_PulseAudio_problems , https://fedoraproject.org/wiki/How_to_debug_sound_problems .
